1. 1.5" SUs (score: 1)
Author: David Christman <dpc@ai.mit.edu>

I have been reading some literature that mentions using 1.5" SUs on modified A-series engines. Would the carbs on a 71 MGB be suitable? Thanks.

Yes, but not the manifolds or the needles - a 1.5 SU is a 1.5 SU whatever it comes off. But, I have heard that generally you will get better results using a single 1.75 carb. Daniel 1312

Twins are better than singles. Whether you need 1.5s is the question. I would suggest you invest in a 'Vizard' book and the Haynes SU book. Together they will give you an idea. Martyn (Ported 948, ri

Hi Martyn, I do not agree that twins are better than singles. What matters is the amount of airflow the engine receives (and requires) and with carbs the amount of air the carb can flow be it a large

FWIW, there are intrinsic performance characteristics to each setup that must be considered for each application. My perspective is SCCA Solo II (or autocross, etc.). This hobby closely approximates

Were the comments re: Weber 45 DCOE for a 1500?? I'd love to hear what anyboy else is running in a 45 on a 1275. I have 34 Main venturi, 35 aux vent., 125-F2 main jets, 50-F9 idle jets. Any comments?

I was just looking at dyno charts in Vizard's book. The results were (don't recall what engine, 1275 or bored 1400) that the Weber 45 was best above 5000 rpm and the 1.75 SU was better below 5000 rpm

If you have access to a chassis dyno and are prepared to pay for time on it, I would go for the DCOE. There is probably not much to choose from the two and it does appear to be personal preference an
